.SH SYNOPSIS

\fBcc\fR [ \fIflag\fR... ] \fIfile\fR... \fB-lpicltree\fR [ \fIlibrary\fR... ]
#include <picltree.h>

\fBint\fR \fBptree_create_prop\fR(\fBptree_propinfo_t *\fR\fIpinfo\fR, \fBvoid *\fR\fIvalbuf\fR,
     \fBpicl_prophdl_t *\fR\fIproph\fR);

.fi

.SH DESCRIPTION
.sp
.LP
The \fBptree_create_prop()\fR function creates a property using the information
specified in \fIpinfo\fR, which includes the name, type, access mode, and size
of the property, as well as the read access function for a volatile property.
The value of the property is specified in the buffer \fIvalbuf\fR, which may be
\fINULL\fR for volatile properties. The handle of the property created is
copied into the location given by \fIproph\fR.  See
\fBlibpicltree\fR(3PICLTREE) for more information on the structure of
\fBptree_propinfo_t\fR structure.
.sp
.LP
The \fBptree_destroy_prop()\fR function destroys the property specified by the
handle \fIproph\fR.  For a table property, the entire table is destroyed. The
property to be destroyed must have been previously deleted.
.SH RETURN VALUES
.sp
.LP
Upon successful completion, \fB0\fR is returned. On failure, a non-negative
integer is returned to indicate an error.
.sp
.LP
\fBPICL_STALEHANDLE\fR is returned if the handle is no longer valid. This
occurs if the PICL tree was refreshed or reinitialized.
.sp
.LP
\fBPICL_INVALIDHANDLE\fR is returned if the specified handle never existed.
